Why your faucet drips
and why it matters
"It only drips a bit" is the phrase that costs us all. Behind it is a worn part and, over time, a bigger bill.
Why it happens
On classic faucets, the culprit is usually a worn washer. On modern single-lever ones, it's the ceramic cartridge. Both are swapped easily, with cheap parts.
What it actually costs you
A frequent drip adds up to tens of liters a day. Over a year, you end up paying for water you never used, plus extra wear on the faucet.
Nothing fixes itself. A drip ignored today is a whole faucet replaced tomorrow.
When it's worth replacing the faucet
If the faucet is old and keeps giving trouble, it's often better to replace it than to keep repairing it. I tell you honestly when it's worth a new one and when a washer is enough.
